I’ve also had a bit of lower back. Pain and felt sick but the doctor figured the sickness was an upper respiratory infection
Oral sex exposes you to syphilis, gonorrhea and herpes. I don't think cottage cheese is the best option to treat yeast infections. The best option is always talking to your doctor and getting a cream to treat them.
Regarding the three infections I told you about, you should test as follows:
-3 weeks after the exposure, for gonorrhea,
-6 weeks after the exposure, for syphilis.
-3 months after the exposure, for herpes.
All the best.
